I'm getting what I believe to be an error code of some kind where I power my laptop on, it flashes the caps lock indicator light for a few seconds, then powers off by itself. Details are below.

On my inspiron 4150, it bluescreened a few days back. Since then, if it has been off for several minutes, it will boot and then freeze at some random point but within a minute or so. This can happen at any point from the boot menu to within windows. However, after it freezes, if I turn it off and then back on, it powers up, blinks the caps lock indicator light for a few seconds and then powers down. I'm guessing this must be some kind of error code. Because the error can happen before windows is done loading, I'm thinking it could be hardware related.

Thoughts would be appreciated...
